E语言是由国家电力调度通信中心开发的电力系统数据模型描述语言。提出了基于E语言的统一的电能量计量系统互联方案,不仅解决了由于二次系统安全防护所带来的跨安全区系统间数据交互困难的问题,而且规范了电能量计量系统互联接口,为电能量计量系统数据互联提供了新思路。结合江苏省电能量计量系统的建设,给出了该方案的具体实现和应用,并针对方案中的不完善之处给出了具体建议。
E language is a power system data model description language developed by the National Power Dispatching and Communication Center. A unified E-metering scheme based on E language is proposed, which not only solves the problem of data exchange across secure zones caused by the secondary system security protection, but also regulates the interconnection of electrical energy metering system as Electric energy metering system data interconnect provides a new idea. Combined with the construction of electric energy metering system in Jiangsu Province, the concrete realization and application of the scheme are given, and specific suggestions are given for the imperfection in the scheme.
